Car Energy Life-Cycle Analysis


The mazda3 car has used approximately 55000 kW-h in about three years. However, the energy use to manufacture this car is approximately 76000 kW-h [1]. Is it worth it? In order to justify the cost of manufacturing, based on about 18,000 kw-hr per year, the car would have to be used for 8 years.  (Note: This energy consumption was based on a consumer's current vehicle in the United States.)
